If you try to do the vaporizing in a small propane tank, the refrigeration effect will cool the propane until it will no longer vaporize fast enough to produce enough vapor to keep the forklift engine running. Without hot coolant flow, the vaporizer will freeze up and quit within a few minutes. Turning liquid propane into vapor has a strong refrigeration effect, that quickly cools the point where vaporization takes place, that's why the vaporizers are heated by engine coolant. I did a poor job of explaning why most feed liquid propane to the engine, where hot engine coolant turns liquid LP to vapor for the engine. I don't know if there is a pressure regulator on the line to the engine but by drawing the incorrect component off the tank you can destroy the regulator. small bottles only discharge vapor in the upright position, if laid on their sides they will give off liquid until the liquid level drops below the outlet point. There is probably a pickup tube in the tank that allows it to either pick up liquid or vapor depending on how the tank is positioned on the fork lift. valve (float ) reached the level of what would be normally full if upright, would then prevent any more from leaving the bottle. Just wouldn't be able to get the tank empty, once the o.p.d. is south of the equator where it's almost summer? Learn something new everyday! I thought you might be irrigating year 'round now? :- ) Surface area of the tank and the ambient temp governs how much vapor you can get out of the tank. I have seen antique tractors running on grill bottles. If it had a larger tank, you could still run on vapor valve. I think it is the other way around, the warmer the propane the faster it will vaporize. The liquid is for on hot days when its pulling hard and not vaporizing fast enough. Don't really irrigate in winter here! : ) It may not do it in the winter like Jon said, but summer when it is warm out not a problem. I once had a pick up that ran on LP and I used a 30 lb bottled turned upside down to get home one time : ) Aluminum forklift bottle off the internet. A LP powered forklift has a vaporizer on it that converts the liquid from the tank to a vapor form that the carb can mix with air to fuel the engine. Maybe you could turn the bottle upside down and get liquid out of it. My pivot motor is running off the vapor valve.

Your forklift needs to run on liquid propane, a forklift tank has a dip tube to withdraw liquid fuel from the bottom of the tank, while a BBQ bottle will only pull propane vapor off the top of the tank. I don't think you can make it work, especially in cold weather. Need a tank with a ? liquid pickup ? tube (I think ) Edited by Angus in ncmo 10:04 I think the regular 20# bottle is vapor only. Has anyone just used a regular 20lb bottle for a forklift? can this be done or am i out to lunch? Posted 09:56 (#1453229) Subject: propane tank on forklift? Propane tank on forklift?
